The SkyMapper Telescope at the Siding Spring Observatory is a state-of-the-art automated wide-field survey telescope that has already made many new discoveries from the chemically most pristine old stars in the Milky Way Galaxy to the fastest-growing supermassive black holes in the early Universe. It is sited under the dark skies of Siding Spring Observatory near Coonabarabran, in central NSW, and operated by The Australian National University's Research School of Astronomy and Astrophysics. Over the decade from 2014 to 2023, SkyMapper created the first comprehensive digital survey of the entire southern sky. The result is a massively detailed record of more than a billion stars and galaxies, to a sensitivity one million times fainter than the human eye can see. The survey's data set is freely available to the scientific and general community via the internet. Currently, SkyMapper is on stand-by for following-up gravitational-wave events, and is also available for dedicated 3rd-party observing programs on a user-pays basis.
